About the same time they domesticated plants (10,000 years ago) people in Mesopotamia began to tame animals for meat, milk, and hides. Hides, or the skins of animals, were used for clothing, storage, and to build tent shelters.
In Mesopotamia. Ten-thousands years ago. And now they talk of making sausages with maggots. That's progress!
Yeah - at some point ten thousand years ago some Sumerian looked up and said, "what, you're eating bugs? That's gross!" And we wouldn't be where we are now if everybody didn't agree with him.
